DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plow working machine, and more particularly, to a plow working machine suitable for a tractor mounted on a tractor by a three-point link.

[0002]

2. Description of the Related Art In recent years, the environment surrounding Japanese agriculture has been demanded for agriculture with improved profitability, in other words, agricultural management due to large-scale farming. Therefore, it is becoming impossible to cope with agricultural work using large-sized working machines. In such an agricultural environment, the working machine tends to be larger as the field becomes larger, and the well-known plow working machine is not an exception but tends to be larger. This plow working machine has a plurality of bottoms attached to a frame which is arranged so as to extend obliquely rearward with respect to the working direction as a whole to constitute a so-called multiple plow working machine. The need for such implements is increasing day by day.
In order to use such a multiple plow working machine, a large tractor, particularly a crawler-type tractor, has come to be used as a tractor capable of expecting a large output. This type of crawler-type tractor employs a hill-pulling type in which both left and right crawlers move on a flat surface, instead of a conventionally known groove-pulling type.

[0003]

In the plow working machine suitable for the hill-pulling type as described above, the lateral pressure when performing the plowing work is large, and the burden weight of the working machine at the leading position in the working direction is also large. It is big. Originally, the side pressure during the work was borne by the land side of each bottom and the inside of the tractor wheel during groove pulling contacting the side wall of the debris groove. In the case of a hill-pulling type using a la-type tractor,
And the crawler itself cannot bear the lateral pressure generated by the work, so that only the land side bears the lateral pressure, and a large land side is required for each bottom, which increases the weight of the working machine. The result is still
The lateral pressure cannot be sufficiently borne. Therefore, there have been problems such as difficulty in stabilizing the posture of the tractor and the working machine during operation. In particular, in the case of hill-pulling work, the working width of the first bottom varies greatly depending on the traveling position of the tractor, and there is no problem if the vehicle can travel along the groove, but it is not a problem. When the vehicle travels at a position away from the gravel groove formed in the previous operation so as not to drop the rubber into the gravel groove, the width of the first bottom to be inverted becomes large, in other words, the amount of soil inverted by the first bottom becomes large. As a result, the soil environment after inversion will not be uniform. Accordingly, the present invention has been designed to cope with the increase in the size of the plow working machine, and to allow the work to be performed in a stable posture at all times, a part of the lateral pressure generated during the work and the weight of the front side of the working machine. It is an object of the present invention to stabilize the posture without increasing the size of the land side by bearing the position of (1).

[0004]

In order to achieve the above-mentioned object, a front frame having an upper link of a tractor, a mast for mounting a lower link, a lower link pin, and the like are provided. A reversing frame mounted rotatably with respect to the frame, and a working machine frame mounted to the reversing frame and having a plurality of bottom units mounted thereon, A stem is attached to the working machine frame at a position outside the working width by the bottom and close to the first bottom, and a tillage width regulating wheel is attached to the stem to be adjacent to the first bottom. It is characterized in that the tillage width regulating wheel is configured to be able to move in the combined gravel groove, and in the mounting position of the upper link and the mast, a long hole is provided. Which is characterized that it is fitted with, in which addition, the plowing width regulating wheel is characterized in that the campus angles are given in the working direction of travel the front view.

In the present invention as described above, in a normal operation, in other words, in a plowing operation in the central part of the field, the tillage width regulating wheel is positioned in a gravel groove formed by the first bottom. As a result, the lateral pressure generated by the plowing work, along with the land side of each bottom, is borne by the tillage width regulating wheel to properly maintain the posture of the plow working machine. The load can be reduced because the tillage width regulating wheel bears a part of the added load. In particular, the work position of the first bottom can be fixed, and whether the inverted soil amount is uniform, in other words,
The soil environment after the reversal can be made uniform. Also,
Since the tillage width control wheel is provided with a camper angle, the rubble wall and the rubble bottom come into contact with the lug, which is the part of the tire that originally touches the ground, causing damage to the crushed soil wall and Tire wear can be prevented.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In these figures, reference numeral 10 denotes the entire bottom plow working machine to which the present invention has been applied. This working machine has a mast 11A for mounting an upper link of a tractor at a leading portion thereof, and a mounting hole of an upper link UL is provided. It has a long hole 11X that is long along the work traveling direction, and the lower end side flanks 11B of the mast 11 are spread in the width direction, and the both ends of the cross shaft 12 for attaching the lower link LL are formed at the ends. A supporting mast frame 11 is formed, and a front frame 14 is attached to the mast frame 11 so as to be rotatable via a bearing 13.

The front frame 14 is a mast frame.
The other end of a retractable cylinder type reverse cylinder 15 whose one end is attached to the mast frame 11 is attached to the front frame 14. In addition, the front frame 14 can be reversed by one extension and retraction stroke of the reverse cylinder 15.

A work machine frame 16 extending obliquely rearward in the working direction is disposed behind the front frame 14. The work machine frame 16 and the front frame 14 are connected to each other. The space is connected by two support frames 17. That is, one end of the two support frames 17 is fixed and protrudes from the front frame 14 in a plane including the work machine frame 16, and the other end of the support frame 17 is provided. The part is the working machine frame 16
It is fixed to.

Above and below the working machine frame 16, a plurality of bottom units 18 for constituting a reverse sprout working machine, for example, five bottom units below the first bottom unit are interposed by beams. The bottom side is equipped with a land side 18X. Further, a gage wheel 19 is attached to the fourth bottom of the work machine frame 16 at a position forward of the work traveling direction via an arm 19A projecting from the work machine frame 16. In other words, the gage wheel 19 is located at the work front position at the final bottom.

[0010] A coater 18A is mounted via a supporting arm 18B at the leading position of each bottom unit 18 in the working direction, and functions as a guide for plowing work by the bottom, and further forward. Has a joiner 1
8C has the same functions as conventional coaters and jointers.

Further, at the end of the working machine frame 16 from the first bottom unit 18, a regulating wheel support arm 21 extends with the working machine frame 16 extended. At the end of the support arm 21, a work machine frame 17 is provided.
A stem 22 extends vertically above and below the stem 22. At both ends of the stem 22, a telescopic extension stem 22A is inserted, and the length of the entire stem is adjusted by adjusting the insertion length of the extension stem 22A. Adjustments can be made. The length is set by inserting a pin into a pin hole. A bearing 23 is attached to an end of the extension stem 22A, and the bearing 23 has a camper angle. This bearing 23
The shaft 24A of the tillage width regulating wheel 24 is supported, and a camper angle is given to support the tillage width regulating wheel 24.

Next, the operation using the plow working machine according to the present invention will be described. First, the posture of the working machine 10 at the start of the work, that is, during the opening operation, the first bottom is stabbed into the surface on the field, so that the load initially applied to the first bottom tends to be extremely large. is there. However, in the opened state, the tillage width regulating wheel 24 is located forward of the first bottom and is in a ground contact state with the field surface. Since the sticking of the bottom is restricted, the sticking is performed from the last bottom, and the excessive load on the first bottom is prevented. Further, there is a long hole 11X at the mounting position of the upper link UL and the mast 11A, and the mounting pin of the upper link is located at the front side of the long hole 11X at the time of opening the mouth to prevent overload of the first bottom. It also provides play and prevents overloading during work.

In addition, in the work in the central part of the field after the opening work, in other words, in the normal plowing work, the tillage width regulating wheel 24 is dropped into the depressed groove R, and the work is started. At this time, since the camper angle is given to the tillage width regulating wheel 24, the original ground contact portion of the tire constituting the wheel comes into contact with the debris wall RH and the debris bottom RB, thereby preventing the tire from being worn. Although the camber angle is not necessarily required as a function of the tillage width regulating wheel 24, the side wall of the tire is a portion that is weak against friction because it is not originally in contact with the ground or the like. The camper angle is effective in protecting that part.

In this state, the tillage width control wheel 24 bears the weight of the portion near the tip of the plow working machine 10 and also bears a part of the lateral pressure during the work. It contributes to stabilization. Furthermore, tillage width control wheel 2
The positioning of the first bottom 4 in the debris groove R also serves as a guide for the work position of the first bottom, so that the work can be facilitated.

In the above description, a tractor to which the plow working machine of the present invention is mounted has been described as a tractor of the crawler type. However, the tractor can be operated by a wheel type tractor, and is a so-called three-point hitch type. Anything can be used.

[0016]

As is apparent from the above description, according to the plow working machine of the present invention, the end of the working machine frame, the first
Since the tillage width regulating wheel supported by the stem is arranged outside the inverted side of the bottom, the load on the first bottom in the rotted state can be reduced, and the working posture of the plow working machine can be stabilized. Can be planned. In addition, the working position of the first bottom can be reliably fixed, and the amount of the inverted soil of only the first bottom does not increase. Further, since the tillage width regulating wheel can bear a part of the side pressure during the operation and the weight of the working machine, it is possible to suppress an increase in weight such as an increase in the size of the land side. Furthermore, by giving a camper angle to the tillage width regulating wheel, the original ground contact portion of the tie or the like constituting the tillage width regulating wheel can be brought into contact with the debris groove, thereby preventing the occurrence of abrasion. Can be.
